To all whom it may concern:'

Be it known that I, Enrrrraijn'r A. Tmrr, a citizen of the United States, residin at Beverly, in thecounty of Essex and. cmmonwealth of Massachusetts have invented certain Improvements in heel-Attaching Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. v

This invention relates to heel attaching machines, and while many features of the invention may be advantageously used in other types ofheeling machines, the invention is herein shown and described as embodied in a machine for attaching certain kinds of heels of the character hereinafter described. I

Boots'andsho'es of certain well-known classes are commonly pro formed of a wooden core havin an .outer lateral covering of flexible material, such as leather or canvas, and a top piece of leather. Heels of this class differ from. those more commonly used, not only with regard to the material of which they are composed, but also in that they are frequently of unusual height and" are generally of considerable pitch. So far as I am aware, heelsof this nature inpractice have been heretofore attached by nails driven by hand. It has been regarded as impractical to attach them mechanically on account of the nature of the material of which they are composed,

which renders them particularly liable to be split or fractured, and also on account of the unusual characteristics as to formwhich they possess. As will be obvious, however,

the manual performance of the operation of securing such heels to shoes requires the expenditure of considerable time, since the driven singly. One object of the present invention accordingly is to provide a machine by which heels of this class may be mechanically attached to shoes, and themanufacture of the shoes thus expedited.

The present invention contemplates the provision of a machine for attaching heels of this class, by nails driven. from within the shoe, although certain features of the invention may be embodied in other types of machines and in machines for attaching other kinds of heels. It,is desirable that died With heels nails which are inserted ina heel shall be so arranged as to hold securely-upon the shoe therear portion of a heel, since at this point when the heel is'of considerable pitch there is liability ofthe heel being forced-away from the shoe by the strain to which the shoe is subjected in use; On account of the pitch of heels bf this class, the tread surface of a heel lies so far in advance of therear of the shoe that the pressure of the nails forced into the heel can not be resisted with suflicient firmness by devices having engagement with-the tread surface to hold the heel from displacement as the nails are driven. Furthermore, on account'of the nature'of the material of the '-heel,'if the'p'ressure t0 which it is subjected is excessive, there is considerable liability of fracturing the heel before the nail is driven. It is important, however, that a heel be held upon its heel seat with sufficientpressure to preclude its displacement in the nail driving operation. If the heel not held firmly upon its seat, the nails which are driven through the sole into the heel may force-the heel away from or' longitudinally of the sole and thus prevent the close relation between the heel and heel seat which is desirable to impart anattractive appearance to the rear portion of theshoe, as well as render the attachment of the heel insecurar "To theiendth'at a heel of the class referred to may beheld securely upon its seat while the nails are being driven, and without subjecting it to injurious strain, an important feature of the present invention consists in the provision ofm'eans, for pressing a heelv upon its "heel seat adapted to exert pressure toward the heel seat upon the surface of the heel intermediate its tread surface and heel seat surface. The provision of means having this function permits a heel to be forced uponits seat by pressure exerted outside the area of its tread surface. The arrangement shown such that the means for pressing a heel uponitsse'at may also exert pressure upon the tread surface of the heel. To secure the best results, pressure upon a heel should be exerted upon its tread surface and upon the sloping surface at the rear of said tread surface. This arrangement permits the rear portion of the heel to be held firmly upon its seat and insures a close fit between the heel and its seat at this point.

. either the in many kinds of work, a longitudinal displacement of the heel upon the heel seat ofthe sole, which it is difficult to overcome by pressure on' the tread surface alone. There is especial liability of such displacement in attaching heels having non-parallel tread and heelseat surfaces, as in machines for attaching such heels the efi'ective surface of work support, or the tread engaging member, or both, will be inclined with respect to the direction of pressure and the heel is, therefore, likely to be displaced when subjected to pressure before the attaching nails are fully driven. High heels having relatively small tread surfaces and non parallel tread and heel seat surfaces are particularly diflicult to attach without displacing them on the sole, and this difficulty is serious when, as is usual, these surfaces c0nverge toward the breast of the heel.

With a view to preventing such longitudinal displacement of a heel while under ressure and before the attaching nails are ully driven, it is another object of the invention to provide a heel attaching machine having means arranged to act upon the end surface of a heel and hold it firmly against the tendency to longitudinal movement.

To this end an important feature of the invention consists in the provision of. an auxiliary heel engaging device having an oblique or inclined face arranged to bear against the rear curved surface of a heel and prevent rearward displacement of the heel.

A further feature of the invention is the combination of such a device with opposed means for applying pressure to the work, which means have non-parallel faces converging toward the breast of the heel.

In the embodiment of the invention to be specifically described hereinafter, the means for exerting pressure on the rear of the heel toward the heel seat also acts to oppose rearward displacement of the'heel longitudinally of the heel seat.

In the operation of heel attaching machines, and particularly those adapted for attaching wood heels, the heels which must be handled are subject to frequent variation in height and in pitch as Well as in size. It is desirable that a machine for attaching heels be capable of adaptation to the particularheels which are to be attached and a further important feature of the invention accordingly consists in arranging the parts for adjustment to accommodate heels varying in one or more of the respects referred to..

The machine hereinafter more fully described comprises a stationary shoe support and movable devices for pressing a heel upon theheel seat of a shoe carried by said support. It will be understood however that it is within the scope of the present invention to press a heel upon its heel seat by movement of the shoe support. The devices longitudinally of the shoe.

shoe.

having engagement with the heel comprise a tread plate for engaging the tread surface of the heel and an auxiliary device at the rear of the tread plate for engaging the heel intermediate its tread surface and its heel seat surface. The tread plate and auxiliary device are mounted upon a vertically movable carriage and are arranged for simultaneous adjustment upon said carriage The auxiliary device at the rear of the tread plate is ar- 1 ranged for vertical adjustment independently of the tread late. is angularly adjustable upon the carriage to permit its acting face to be given different degrees of inclination longitudinally of the The several adjustments permitted the tread plate and auxiliary device allow heels varying in size or contour to be securely held in position while the nails are being driven. In the embodiment selected for, purposes of illustration the shoe support is provided with internally arranged drivers for driving nails from within the shoe through the sole into the heel.

Other features of the invention will be hereinafter described.

In the drawings, which illustrate a machine constituting one embodiment of the invention, Figure 1 is a view in side elevation, with parts in vertical section, of said machine; 'Fig. 2 is'a view on an enlarged scale in side elevation with parts in vertical section of a portion of the machine shown in Fig. 1; Fig. 3 is a perspective view illustrating details of construction of the treadle mechanism; Fig. 4 is a View in front elevation of the machine shown in Fig. 1; Fig. 5 is a view in perspective of actuating mechanism for the carriage hereinafter described;

The tread plate Fig. 6 is a vertical sectional view taken transversely through the upper part of the work support Fig. 7 is a perspective view of drivers employed in the machine; Fig. 8

'is a view illustrating clutch mechanism for controlling the operation of the machine.

Referring to the drawings, 2 indicates a suitable frame provided with a forwardly projecting bracket upon which is secured, in fixed position, a vertical shoe support 4 the upper end of which is formed to enter a boot or shoe and sustain the same in working position. The shoe support is provided at its upper end with vertically arranged driver passages in which are received drivers carried by a driver bar 6, said bar being arranged within a vertical bearing formed within the shoe support. A spindle 8 is mounted for vertical movement in a suitable bearing in the frame 2 and is provided at its upper end with a head 10 having'a vertical bore formed to receive the lower end of the driver bar 6. The head 10 is provided with a transversely? extending recess in which is arranged an adjusting nut 12 which cotiperates with the screw-threaded lower .formed upon to secure vertical adend of the driver bar A spring-pressed pin justment of said bar.

'14 may be provided to hold said nut in position. The spindle 8 is connected by means of a link 16 to a crank secured upon the forward end of the driving shaft 18.

Arranged for vertical sliding movement upon the frame 2 at its upper end is a head or carriage 20. Said carriage is guided in its movement by a vertical guideway upon saidframe in which are received ribs 22 the carriage. The carriage is moved vertically in its guideway and maintained in its working position by mechanism to be hereinafter described under the control of the operator.

A slide 24 is mounted in horizontal grooves 26 in the head or carriage 20, an adjusting screw 28 being provided to facilitate adjustment of the slide and to hold it in its adjusted position. Upon the slide 24 is arranged a tread plate 30 secured to the slide by a dove-tail and groove connection. As will appear from Fig.2, said connection is circularly curved in order to permit the lower face of the tread plate to be inclined at any desired angle, longitudinally of the shoe. The slide 24 is provided with a clamping section 32 which may be ressed against the tread late 30 by a thum screw 34 to hold said p ate in its ad'usted position.

At the rear of the. tread plate 30 is arranged an auxiliary device for engaging the rear end of a heel. Said device comprises a stem 36 arranged for vertical adjustment in the slide 24 by means of a screw 38 and provided at its lower end with a forwardly inclined orwedge-shaped portion having securved thereto elastic material 40, such as rubber, which prevents slipping of the wedge-shaped portion on the heel and conseuent marking thereof. As will appear om Figs. 2and 4 the lower face of said material is laterally concave and is inclined upwardly and forwardly in order to conform roughly to the shape of the rear end of a heel. The auxiliary device is held rigidly against rearward movement by the rear wall of the guideway in which the stem or slide 36 is'mounted andits inclined surface prevents rearward displacement of the heel.

To actuate the carriage 20 carrying the tread plate 30 and auxiliary device 36, the frame 2 is provided at its upper end with a shaft 42 carrying a spiral cam 44 which engages a cam roll 46 upon the upper end of the carriage 20. To the shaft 42 is secured a pinion 48, meshing with a rack 50 which is arranged for vertical movement in a suitable guideway and is connected to treadle mechanism by means of a treadle rod 52. It will be seen that by depressing said rod the carriage 20 will be forced downwardly by the cam 44. To return the carriage to its raised position there is provided a spring 53 and .to return the cam 44 to its initlal position a coiled spring 54 is arranged about the shaft 42 to rotate said cam in a left-handed direction, viewing Fig. 1. To limit upward movement of the carriage a stop comprisin a vertically adjustable screw 56 is provide secured in fixed position by a binding nut 58.

The treadle mechanism for depressing the carriage 20 comprises a lever 60 ,pivoted upon a stud 62 upon the base of the frame 2, the treadle rod 52 being pivotally connected to said lever. the operator is also pivotally mounted upon the rod 62 and is provided with a curved slot through which extends a clamping screw 65 entering a threaded hole in the lever 60. The meeting faces of the bar 60 and the arm 64 are serrated as will appear from Fig. 4. It will be seen that the arm 64 may be adjusted upon the lever 66 into different elevations by releasing the clamping screw 65.

The starting and stopping mechanism, which is shown herein, comprises a clutch arranged to transmit movement from the wheel 66 to the shaft 18, said clutch being controlled by a dog 68. A bell crank lever comprising arms 7 0 and 72 is pivotally mounted upon the frame 2 and is held normally in the position shown in Fig. 8 by means of a spring moved from beneath the dog 68 produces operative connection between the shaft 18 and the driving wheel. The arm 72 is engaged b a rod 76 connected by a link to a hand ever 78 mounted within convenient reach of the operator upon the machine frame, and held yieldingly in raised position by means of a spring. The lower end of the rod 7 6 is pivotally connected to a lever 80 arranged for movement about a shaft 82. The rod 76 is provided with a notch 77 in which is received a stud 7 9 upon the arm 72. It will be seen from Fig. 8, that when the said rod is depressed the arm 70 is moved outwardly from operative relation to the dog 68 and that at the same time the lower end'of the rod 76 is moved outwardly in the downward movement of the lever 80, and the studcarried by the arm 7 2 is moved slightly inwardly. The arrangement is such thatimmediately after the arm 70 is moved from beneath the dog 68 the rod 76 is disengaged from the stud upon the arm 72 and the arm 70 is allowed to be returned to its initial position. The driving shaft 18 is thereby given one complete rotation and der that an increased pressure of the brake thereon may be produced as the shaft 18 approaches the end of its rotation.

An arm 64 for engagement by 74. The arm 70 when re- In the use of the machine shown, it will be understood that the shoes operated upon have previously been prepared for the re.- ception of heels in the manner customary in nailing them by hand. This-consists in manually cutting away the outersole along the margin of the heel seat in order that the concave heel sea-t face of the heel may lie in close relation to the heel seat, and the edge of the heel thus be in close proximity to the counter of the shoe. been thus fitted to a shoe it isplaced with that particular shoe for subsequent attachment thereto. a

The operator of the machine herein described having inserted the desired number of nails in the nail cavities of the shoe support, places a shoe upon the support. The heel. to the heel seat face of which glue has been previously applied, is then positioned by the operator upon its seat. A proper positioning of the heel is facilitated by shoulders previously formed in the edge of the sole at the breast of the heel in 'thetrimming operation above referred to. The tread plate and auxiliary device 36 may be then brought down upon the heel and such adjustment effected as maybe necessary to suit the particular form of heel being attached. The tread plate is angularly adj usted upon its support to conform approximately to the inclination of the tread face of the heel. Where a heel such as is shown in Fig. 2 is employed, the tread surface of the heel is considerably inclined longitudinally of the shoe, with relation to the heel seat. If desired, the tread plate 30may be given such angular adjustment that it bears only upon the rear portion of the tread surface of the heel. This is of advantage in that it tends to force the rear part of the heel more firmly upon its seat than would be the case if the tread plate engaged the tread surface uniformly over its entire area. The auxiliary device 36 may be then adjusted into the position in which it bears most effectively on the rear portion of the heel. The horizontal adjustment permitted by the adjusting device 28 and the vertical adjustment permitted by the adjusting device 38 permits the inclined face of the device to be brought into engagement with the rear portion of the heel whatever may be the contour of the latter. I

The parts being adjusted in proper manner, the pressure device is brought firmly down upon the heel and the nails are automatically driven when the machine is started by depressing the lever 7 8, pressure being maintained upon the treadle meanwhile'tmhold the heel against the thrust of the drivers. The ends of the drivers are beveled as will appear from Figs. 2 and 7 so that the nails at the sides are inclined inwardly and a nail driven by either of the A heel having further adjustment of vertical adjustment of the,

'two rear drivers is inclined forwardly. It

will be understood that the number of nails inserted at a single operation may be whatever desired, within the limits of the number of drivers employed. Adjustment of the tread plate and auxiliary been effected for a certain kind of heel, no course is required in Where a change in size of heel is made, without other change such as in height or pitch, the machine may be prepared for operating upon the new size by nailing such heels.

device 36 having merely adjusting the carriage 20, out or in.

When change in height or pitch is made, member 36, as well as horizontal adjustment of the carriage 20 and tread plate may be required.

The position of the group of nails inserted in the heel may be varied by shifting the shoe upon its support. The horizontal adjustment of the slide 24 allows this to-be conveniently done, since after and member 36 have to fit a heel the position of the heel and shoe upon the support maybe varied by shift-ing the slide 24;. It will be seen that after being properly adjusted the tread plate and auxiliary device 36 constitute a positioning device for positioning the shoe and heel.

It will be observed that the initial position of the carriage 20 may be varied by adjusting the stop 56. This may be required where the height of the heel is varied, since it is desirable that the movement of the carriage 20 required to bring the tread plate and device 36 into engagement with a heel shall not be excessive. The adjustment of the the tread plate angular adjustment of the,

been adjusted relatively, I i

treadle arm 64 allows the part engaged by the operator to be ient for actuation, the initial position effected.

The mechanism for depressing the darriage 20, which is shown on the drawings, is constructed to. permit said carriage to be given a position convenwhatever adjustment in of the carriage 20 be rigidly held by the operator against the thrust of the drivers. Thereis consequently no liability of the heel being moved vertically in the nail driving'operation through movementof'said carriage.

The use of the machine shown permits the time required for attaching wood heels to be materially shortened, not only because less time is required for driving the nails than is required where they are inserted. manually, but alsg because the heel is forced firmly upon its seat by the pressure imparted to it. Heretofore, in order to bring a heel into close contact with the seat, it has been a common practice after the nails are driven to subject a shoe and heel to pressure in a suitable press, the shoe being left in the-press for a short interval of time to permit the glue applied to the heel seat face .jju

of the .heel to set. By the employment of the present machine, the necessity of subjecting a shoe and heel to a pressing operation after the nails are driven is obviated, the pressure ap lied to the heel in the use of the machine being sufficient to bring the heel into the desired close relation to its seat.

The tread plate 30 is preferably arranged upon its support, so that it may be angularly ad'usted about an axis approximately coinci ent with the lower rear corner of said plate. This is ofadvantage in that it permits vertical adjustment of the device 36 without interference with the tread plate in whatever inclination the lower face of said plate may lie. The arrangement shown is such that the tread plate may be self-adjusting into proper angular position since, after the clamping screw 84 has been loosened, when the plate is forced upon the heel said plate tends to assume a position conforming approximately to the inclination of the tread surface.
